Order of Operations

The TI-34 MultiView™ calculator uses Equation Operating System (EOS™) to evaluate expressions. Within a priority level, EOS evaluates functions from left to right and in the following order.

1st

Expressions inside parentheses.

2nd

Functions that need a ) and precede the argument, such as sin, log, and all R³´P menu items.

3rd

Fractions.

4th

Functions that are entered after the argument, such as x2 and angle unit modifiers.

5th

Exponentiation (^) and roots (xÑ).

Note: In Classic mode, exponentiation using G is evaluated from left to right. The expression 2^3^2 is evaluated as (2^3)^2, with a result of 64.

In MathPrint™ mode, exponentiation using G is evaluated from right to left. The expression 2^3^2 is evaluated as 2^(3^2), with a result of 512.

The TI-34 MultiView™ calculator evaluates expressions entered with F from left to right in both Classic and MathPrint modes.

6th

Negation (L).

7th

Permutations (nPr) and combinations (nCr).

8th

Multiplication, implied multiplication, division.

9th

Addition and subtraction.

10th

Conversions (n/d³´Un/d, f³´d, ´DMS).

11th

< completes all operations and closes all open parentheses.
